How it's used

This phrase functions as a polite or slightly formal way to introduce information that the listener might be unaware of. It carries a subtle tone of revealing a secret or correcting a misconception, rather than simply stating a lack of knowledge. While it appears in spoken Cantonese, it is often used when the speaker wants to sound more measured or authoritative.

Examples

There might be something about this matter you do not know.
Regarding his background, is there something you don't know?

Common mistake

Learners often mistake this for a simple way to say I do not know, but it is actually used to suggest that the listener is missing information. It is not a direct translation of I do not know, which is better expressed as 唔知.
